- A further object of the invention is to provide a. nail trimming toolof a rotary characterincluding cutting members whereby the nails may be'pared and an abrading disk by' may be imparted to means of which polishthe trimmed edges. I

Further objects of the invention are to simplify and improve theconstruction and operation of this class of devices.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same'consists in theimproved construction and novel arrangement and. assemblage of partswhich will be. hereinafter fully described and particularly pointed outin the claims.

that no limitation is necessarily madeto the I recise structural detailstherein exhibited,

ut that changes, alterations and modifica tions within'the scope ofthe'invention may be resorted to, when desired.

The body of the'improved device-consists of a cylindrical casing 1preferably provided with a permanent closure at one end. as shown at 2and having at the oppos te end a detachable cap or cover 3 which may bein the nature of a screw-cap so as to bereadily detached and applied.The closure 2 and the cap 3 afford bearings for a s 'rally threadedshaft 4 which is supported or rotation in its bearings and whichcarries, adjacent -to and 10 throug slotted cylindrical casing,

- side walls. of the casing 1 and the closure 2 of,

the latterare' rovided with arcuate slots 9 which the ends of the fingernails may be inserted and held in the path of the. cutters 7 and theabrading disk 5' when said members are rotated so that the nailspreferably arcutae in will be trimmed thereby, asv will be readilyunderstood. I

Rotary motion is imparted to the spirally threaded shaft 4 and the partscarried thereby by means of a reciprocatory disk or nut 11 engaging thethreaded ortion of said shaft and provided with a.y-o e' or handle 12,the

side members of which extend through apertures 13 in the cap 3; saidyoke being pro vided at its outer end with an eye; 14 whereby it ma y bemanipulated by the thumb of one hand to impart reci rocatory motion tothe nut 11 which will t us serve to rotatethe shaft 4 within the casing,which is meanwhile bein held by or between the fingers of one hand the'other hand are presented to the t tools through the .apertures or slotsin the casing. I

From the foregoing description taken in connection withthe drawingshereunto annexed, the o eration and advantages of this invention will bereadily understood. The

of the operator, while the fingernails of device isvery simple inconstruction, neat in appearance and efficient in o eration, and it maybe readily manufacture at a moderate expense. By the use of this device,the nails may be trimmed or pared, and the. edges polished absolutelywithout danger of injurthe skin of the finger tips.

what l claim is:

1. In a device of the class described, 'a a shaft supported for rotationtherein, and cutters sup orted upon's'aid shaftadjacent to theslotted othe casin r 2. In a evice of the class described, a

aving fully described the invention,

walls IIO cylindrical casing having slots in the side walls and endsthereof, a shaft supported for rotation in the casing anddevices'mounted upon said shaft for trimming the ends of finger nailsinserted through the slots or apertures.

3. In a device of the class described, a cylindrical casing having slotsor apertures, a detachable cap at one end of the casing, a shaftsupported for rotation in said cap and in the'opposite closed end of thecylinder or casing, and nail'trimming devices carried by said shaftadjacent to the slots and the casing.

4. In a device of the class described, aeasing, a shaft extendingtherethrough, nail trimming devices upon said shaft, and means forrotating the latter; said casing being provided with slots for thepresentation of the ends of nails in the path of the trimming devices.

' 5. In a device of the class described, a slotted casing havin adetached cap, a spirally threaded sha t supported for rotation in thecap and in the opposite closed end of the casing, nail trimming devicescarried by said shaft adjacent to the slots in the easing, a nutengaging the spirally threaded shaft, and means for reciprocating thenut to rotate the shaft.

6. In a device of the class described, a casing having a detachable cap,a spirally threaded shaft supported for rotation in the cap and in theopposite closed end of the easing, nail trimming devices carried by theshaft adjacent to the slots in the casing, a nut engaging the-spirallythreaded shaft, and a yoke connected with the nut, extending through thecap and having a terminal eye.

In testimony whereof, I affix my signature in presence of two Witnesses.
